我正在尝试将一些Hibernate功能添加到Spring Web应用程序中。这是我第一次使用Hibernate会话工厂以某种方式独立于Spring（我使用Hibernate模板并且工作正常）。现在我得到了这些异常org.hibernate.MappingException: Unknown entity，尽管我认为组件连接良好。但是说得够多，让我们给你看一下代码：
实体类：
@Entity // javax.persistence.Entity;
@Table(name = "CreazioneV49_Users")
public class User implements Serializable {
private long id;
private String name;
private String sessionId;
@Id
@GeneratedValue
@Column(name = "USER_ID")
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
@Column(name = "USER_NAME")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Column(name = "USER_SESSIONID")
public String getSessionId() {
return sessionId;
}
public void setSessionId(String sessionId) {
this.sessionId = sessionId;
}
}
存储库类：
@Repository
@Transactional
public class DBUtil implements DBUtilInterface {
@Autowired
@Qualifier("mySessionFactory")
private SessionFactory sessionFactory;
private Session currentSession() {
return sessionFactory.getCurrentSession();
}
public void addUser(User user){
currentSession().save(user);
}
}
Spring Bean组件：
@Component
@Scope(value = "session")
public class CreateV49 implements Serializable {
@Autowired
private DBUtilInterface dbUtil;
public DBUtilInterface getDbUtil() {
return dbUtil;
}
public void setDbUtil(DBUtil dbUtil) {
this.dbUtil = dbUtil;
}
public void persistData(){
User user = new User();
user.setName("Gigel");
user.setSessionId("1545645645646");
dbUtil.addUser(user);
System.out.println("GOOOD");
}
applicationContext.xml的一部分

如果在DB中找不到表，是否可能抛出此错误？

我现在要用<property name="annotatedClasses">而不是包来试试......虽然工作会很奇怪。
似乎使用annotatedClasses工作......用户bean被识别但我收到一个奇怪的错误，虽然我的ID是自动生成的：
Hibernate: insert into CreazioneV49_Users (USER_ID, USER_NAME, USER_SESSIONID) values (null, ?, ?)
Nov 16, 2011 10:44:21 AM org.hibernate.util.JDBCExceptionReporter logExceptions
WARNING: SQL Error: 1400, SQLState: 23000
Nov 16, 2011 10:44:21 AM org.hibernate.util.JDBCExceptionReporter logExceptions
SEVERE: ORA-01400: cannot insert NULL into ("SELIR"."CREAZIONEV49_USERS"."USER_ID")
我正在使用Oracle，所以我在User bean中为我的ID添加了一个序列生成器，但没有成功：
@Id
@SequenceGenerator(name = "my-creazioneV49Seq", sequenceName = "creazioneV49Seq")
@GeneratedValue(strategy = GenerationType.AUTO, generator = "my-creazioneV49Seq")
@Column(name = "USER_ID")
public long getId() {
return id;
}
已解决：升级到隐藏3.6.8并改变对ORACLE的方言！
答案 0 :(得分：2)
我想你需要尝试
<property name="annotatedClasses">
<list>
<value>creazione.persistence.User</value>
</list>
</property>
答案 1 :(得分：0)
您需要persistence.xml列出应该映射的类，或者orm.xml列出包含实体类所在包的包标记的{{1}}。
